This webpage contains a collection of interactive mathematical visualizations built using
MathBox: a library for rendering presentation-quality math diagrams in a browser using WebGL, built on top of Three.js
and ShaderGraph. Most examples also utilize dat.gui for the user interface.
This collection is hosted at GitHub.
